Twofish is a block cipher and can't me turned into a stream cipher.
Stream ciphers are a different class of algorithm. Well, you may use
CFB mode which has similar properties.
Why do you want to use a stream cipher at all. Correct use of stream
ciphers isn't easy. Before you start to do something like this you
definitely should get your hands on literature (no, Applied
Cryptography isn't enough - get Ferguson and Schneier's Practical
